I've been playing around with a Harbinger build in WvW using the Twisted Medicine trait so I can give some boons from my elixirs to allies, and I noticed that the heal elixir does not give the regeneration boon to my allies, and only to myself. I think the other elixirs are giving their boons to my allies, but I have never seen any heal numbers from the regen on my allies when I throw down the elixir on top of us. Is this intended to not grant any regen to others, or is it a bug?
